CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 293,053, dated February 5, 1884.

Application filed May 4, 1883. (No model.)

Be it known that I, FRANK. L. McQUIsroN, of Greencastle, in the county of Jasper and State of Iowa, have invented a new and useful Improvement in Oar-Oouplings, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a plan view of my improvement. Fig. 2 is a front elevation of the same. Fig. 3 is a side elevation of the same, partly in seei-ion through the line mm m, Fig. 1. Fig. 4 is a side elevation of a twisted link.

The object of this invention is to facilitate the operation of coupling and uncoupling cars and promote security in such operation.

The invention consists in a carcoupling constructed with a draw head having attached to it a cross-bar provided with bearings, in which slides a rod provided with stop-pins and a spring, and carrying a coupligg-pin bent to pass horizontally through the draw-head, and a link raising elbow; as will be hereinafterfully describec A represents the draw-head, which is secured in the ordinary manner to bars 13, attached to The draw-head A is made like the draw-head of an ordinary carcoupling, except that the opening for the link is so made as to receive a link standing in a vertical plane, or edgewise, instead of lying horizontally, and also has a recess in its lower side.

To the ,lower side of the draw-head A, at a little distance from its forward end, is secured a cross-bar, D, to the forward side of which are attached arms or bearingsllto receive the rod F, that'carries the coupling-pin G. The coupling-pin G is bent at right angles,

and passes horizontally through the drawhead A and through the coupling-link 1-1,.

placedwithin the said draw-head.

Upon the shank of the coupling-pin G is formed a sleeve to fit upon the rod F, and which has a short slot formed in it toreceive the pin or screw I, to cause the said rod to carry the said coupling-pin G with it in its longitudinal movement, while allowing the said rod to have a partial revolution within the said sleeve. The longitudinal movement of the rod F in one direction is limited by the shank of the pin G striking against the side of the draw-head A, and in the other direction by the sleeve of the pin G, or by a stop-pin,.J, attached to the said rod, and which strikes against one of the bearings E, the said stop being arranged in such a position as to stop the movement of the said rod F before the coupling-pin G has been fully withdrawn from the hole in the draw-head A. The rod F is held forward, holding thepin G in a coupled position, by a spiral spring, K, placed upon the said rod F, with one end resting against the bearing E, and its other end resting againsta pin. L, or other stop, attached to the said rod F.

To.the rod F is attached an elbow, M, in

such a position as to be directly below the recess in the lower side of the draw-head A, .n

turning the rod F; the elbow M will be brought 4 into position to rest against the side of the draw-head A and lock the said coupling-pin G in an uncoupled position.

The cars are coupled by turning the rod F to withdraw the elbow M from the side of the draw-head A and allow the coupling-pin G to be forced through the said draw-head and the coupling-link H by the action of the spring K.

The rod F isprovided with handles N, for convenience in turning it to couple and uncouple the cars.

A car provided with my improved coupling canbe coupled with a car having an ordinary couplingby using a link made with a halftwist, as shown in Fig. 4.

Having thusfully described my invention, I claim as new and desire to secure by Letters Patent l. A car-coupling constructed substantially as herein shown and described, and consisting of the draw-head A, the cross-bar D, having bearings E, the rod F, having stop-pins I J L, the spring K, the elbow M, and the bent coupling-pin G, as set forth.

2. In a car-coupling, the combination, with the draw-head A, of the sliding rod 1?, having stop-pins I J L, the spring K, the elbow M, and the bent coupling-pin G, substantially as herein shown and described, whereby the ears I can be coupled by operating the said rod, as set forth.

3. In a car-coupling, the combination, with the draw-head A, having a recess in its lower side, and thesliding rod F, carrying the bent couplingpin G, of the elbow M, substantially as herein shown and described, whereby the link can be guided into the draw-head of an adjacent car, as set forth.

4. In a car-coupling, the combination, with the slide-rod F, having pin I, and the coup- 15 ling-pin G, having slotted sleeve, of the linklifter M, whereby the link may be lifted without moving the pin, as described.
